Mobile Retailing and Location Aware Applications

The location based services market is forecast to reach $21 billion by 2015.  Location aware mobile applications can provide the potential for many businesses to reach mobile users at the right time and in the right place.  What does this mean?  It is 11:45 a.m. and you are thinking about lunch.  If an email or text message arrives to your smartphone with a coupon for your favorite sandwich at the restaurant just a block from your office, there is a very good chance that you will eat there.
